I am attempting to build Valgrind locally and notice that the output from running configure is:
Maximum build arch: amd64
Primary build arch: amd64
Secondary build arch: x86
Build OS: darwin
Primary build target: AMD64_DARWIN
Secondary build target: X86_DARWIN
Platform variant: vanilla
Primary -DVGPV string: -DVGPV_amd64_darwin_vanilla=1
Default supp files: exp-sgcheck.supp xfree-3.supp xfree-4.supp darwin10-drd.supp darwin11.supp
I'm running on a MacBook Pro with an Intel i7 CPU (running OS X 10.7.4), so I'm not sure why the primary build arch is amd64.
Does anyone know why I'm seeing this?

If I am not wrong, it is amd that defined the extension of the x86 to 64 bits, and so that is one (the?) reason to call it amd64. See also http://www.valgrind.org/info/platforms.html So, no problem.

Ah, ok, thanks for the clarification.

Total red herring. "amd64" is merely the name used to denote "64 bit x86". Works fine on Intels too. J |
